I primarily had $acl_ variables in mind. "strict_acl_vars" is a fairly
new option, isn't it? I'm using a somewhat old exim , so it may not be
relevant (maybe it's time for an upgrade again ;-)). Also, I'm presuming
this option is off by default, so that I won't get surprises as and when
I install a version where it's supported.

Still, maybe I ought to initialise the variable(s) by hand in order to
be on the safe side...

Thanks.
